Device for use in artificial insemination



Aug. 17, 1954 c. J. WESTERMAN DEVICE FOR USE IN ARTIFICIAL INSEMINATIONFiled Dec. 5, 1952 INVENTOR. CYRIL J. WESTERMAN Patented Aug. 17, 1954UNITED STATES PATENT OFFICE DEVICE FOR, USE IN ARTIFICIAL INSEMINATION 3Claims. 1

The object of my invention is to provide a device for use by animalbreeders and more particularly by hog breeders.

The art of artificial insemination has been successfully practiced bybreeders of horses and cattle, but not successfully by breeders of hogs,and it is the object of my invention to provide a device that comprisesa soft, pliable inner liner within a rigid outer enclosure and employingair pressure to permit the soft, pliable inner liner to assume the shapeand contour in close contact with the organ of the male, and theapplication of heat applied to the soft, pliable inner liner tocorrespond with the natural temperature of the vagina of the femaleduring the venereal act.

Hitherto, the artificial insemination of hogs has not provensatisfactory with the devices thus far provided, due to the particularshape of the male organ. The device described, illustrated and claimedherein provides an artificial vagina that is so constructed that it willconsummate the venereal act to a completion and will accumulate the fullvolume of semen for propagating purposes where it may be retained in afecund condition for use in artificial impregnation and semen fromselected and proven male hogs may be suitably conditioned and held undercontrolled conditions which are well known in the art.

Obviously, the veterinarian will employ the proper sterile tubes andguns for introducing the semen taken from my device into the vagina ofthe female and when the proper sterilized tubes are employed the bull:supply of semen will not be contaminated.

The device is simple in construction, easily manipulated manually and isdesigned primarily for sanitary efficient performance.

Other and further objects of my invention will become more apparent asthe description proceeds when taken in conjunction with the drawing, inwhich Figure 1 is an outside view of the assembled device, and

Figure 2 is a fragmentary longitudinal crosssectional view of theassembled device.

Similar characters of reference indicate corresponding parts throughoutthe several views, and referring now to the same, the character Hi,shows a tubular enclosure constructed of semirigid material, such asrubber or the like. This tubular enclosure is open at both its ends andhas an air inlet H extending through its wall. The inlet I! may beprovided with a valve (not shown) or it may be made of pliable materialhaving a self-opening and closing portion. There is a tubular waterinlet shown as l2 having a sealing means l3 which may be a stopper madeof any suitable material.

An inner liner or tube I4, constructed of a soft, pliable material suchas is commonly referred to as latex is shown longitudinally suspendedwithin the outer tube ill and has its ends l5 and I5 folded over theopen edge of the tube In and retained in close contact with the outerperipheral surface of the tube It by means of elastic bands shown as itand I6 which are made of rubber or the like.

A pliable bag member I! open at one end and closed at the other end I8,is constructed of a pliable material and has its open end expanded andslidably placed over the band it holding the open end of the inner linerit. The elastic construction of the bag ll makes it an air tight andliquid tight seal with the liner I l thereby constructing a continuousenclosure open at only one end 19.

For the protection of the pliable bag I1, I show a tubular member 263,open at both ends and having one end 2| in close contact with theexpanded portion of the bag ll and the other open end 22 permitting theclosed end l8 of the bag IT to protrude therefrom.

When in use, warm liquid corresponding to the body temperature of thevagina of the female, is forced into the tubular opening [2. This liquidwill be disposed between the tube It and the inner liner Hi. When themale organ is inserted into the liner [4 through the opening I9 air isforced through the tubular member H thereby forcing the liner 14 awayfrom the inner surface of the tube is as shown by the dotted lines inFigure 22, causing the inner liner to be brought into contact with, andassume the contour of, the male organ and during the venereal act aconstant frictional contact is maintained therewith.

After coition at the completion of the act, the semen will be depositedwithin the bag portion I I which may then be removed from the tube It!and single charges of semen thus collected may be parcelled out amongseveral females by use of the conventional tubes and guns as previouslydescribed, thereby reducing the cost of service.

While I have shown a particular construction and arrangement of thecomponent parts constituting my device, I am fully cognizant of the factthat many changes in the form and configuration of the component partsmay be made without effecting the efficiency of the device and I reservethe right to make such changes as I may deem necessary or convenientwithout departing from the spirit of my invention or the scope of theappended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent in the United States is:

1. A device of the character described colprising, a cylindrical outershell open at both ends, a pliable inner tube open at both ends, saidinner tube disposed longitudinally Within said outer shell and havingits open endslcontacting the open end of said outer shell, a tubular airinlet member, a tubular liquid inlet member, said tubular membersextending through thewvall of said outer shell, in combination with abag member, said bag member being of pliable material open at one endand closed at the other end, the open end of said bag member encirclingthe outer edge of one end of said outer shell and inner tube assembly,means for retaining the open end of said bag member onto one end of saidouter shell, a guard member of semi-rigid material, said guard memberopenat both ends and of a diameter larger than said bag member, one endof said guard memberattached tothe end of said outer shell at the pointof attachment of said bag member to said shell.

2. A device of the character described comprising in combination, atubular outer shell of semi-rigid material, said outer shell open atboth ends, a pliable inner tube of a smaller diameter disposedlongitudinally within said outer shell, said inner tube open at bothends and having its ends contacting the open end of said outer shellthereby .iorming an enclosure between the outer surface of said innertube and the inner surface of said outer shell, which enclosure issealed at both ends, an air inlet tube, a liquid inlet tube, both ofsaid tubes extending through the Wall of said outer shell of saidenclosure, a bag member open at one end and closed at the other end, theopen end of said bag member attached to one open end of said outer shelland inner tube assembly, means for retaining said bag member inposition, and a tubular support extending over the outer surface of saidbag member, said support disposed at one of its ends over the attachmentof said bag to said outer shell and inner tube assembly.

3. A device of the character described, comprising an outer shell ofsemi-rigid material, said shell open atboth its ends, a pliable innertube openat both ends, said inner tube longer than said outer shell andlongitudinally disposed Within said shell, the open ends of said innertube folded outwardly onto themselves over the outer surface of saidouter shell at both ends, forming an enclosure between the outer surfaceof said inner tube and the inner surface of said outer shell andsealedat both of its ends, a pair of tubular ports extending through the wallof said outer shell and leading into said enclosure, elastic means forretaining the ends of said inner tube in position over said outer shell,in combination with a bag member closed at one end and open at theother, the open end of said bag member attached to one of the open endsof said outer shell and inner tube assembly, a tubular guard member ofsemi-rigid material, said guard member open at both ends and of adiameter larger than the bag member, one end of said guard memberattached to the end of said outer shell at the point of the attachmentof said bag member to said shell.
